Nicotine Strength Guide So you've decided to start vaping but you're unsure what nicotine strength you need.

The amount of nicotine you opt to use depends on what you prefer. This is why there are different nicotine levels available, so that you pick the one that is just right for you.

However, when you are transitioning to e-cigs, health professionals recommend that you start off with nicotine levels that are equal to the product you were using before.

For instance, if you were in a habit of smoking: 10 lights cigarettes daily, you can go for 6mg nicotine strength. This is because a light cig usually has around 0.7 mg of nicotine. Once you get into the vaping process, you can start to reduce the levels of nicotine slowly and finally get to the zero nicotine content if this is your goal.

If you was smoking 20 cigarettes a day +, we would recommend 18-20mg nicotine salt 50VG/50PG on a pod system device and gradually lowering down the content. For some this may be too much strength so it depends on the individual. Some pack a day smokers are happy to stick with 12mg but may find themselves using the vape device more often to compensate for the nicotine strength.

Here is a guideline we recommend to people new to vaping:

  • 1-5 cigarettes a day - 3mg nicotine strength
  • 6-10 cigarettes a day - 6mg nicotine strength
  • 11-20 cigarettes a day - 12mg nicotine strength
  • 20+ cigarettes a day - 18-20mg nicotine strength

Below we will show you exactly how we calculate our results with short fills along with a table below for common mixtures.

We will also show in a table below common results when adding different strengths to 25ml, 40ml, 50ml, 80ml 100ml and 150ml short fill bottles.

TO CALCULATE TOTAL NICOTINE STRENGTH

Let’s work out how much the final nicotine strength is when adding nicotine booster shots.

Example 1: 2x 10ml nicotine shots 18mg into a 50ml short fill.
We take the total amount of nicotine first then divide it by the total amount of e-liquid.
For this example it would be [36]mg and [7]0ml total.

How we can calculate this is: [36/7] = 5.14mg


Example 2: 3x 10ml nicotine shots 18mg into a 150ml short fill.
For this example it would be [54]mg and [18]0ml total.

How we can calculate this is: [54/18] = 3mg


Example 3: 1x 10ml nicotine shots 18mg into a 80ml short fill.
For this example it would be [18]mg and [9]0ml total.

How we can calculate this is: [18/9] = 2mg
25ML SHORTFILL E-LIQUIDS

The below table shows a number of different results using nicotine shots in a variety of strengths for a 25ml shortfill e-liquid in a 35ml bottle.

Nicotine shot (ml) Nicotine Strength (mg/ml) Shortfill (ml) Results(mg/ml)
10ml 9mg 25ml 35ml total @ 2.57mg/ml
10ml 15mg 25ml 35ml total @ 4.28mg/ml
10ml 18mg 25ml 35ml total @ 5.14mg/ml
10ml 20mg 25ml 35ml total @ 5.71mg/ml

40ML SHORTFILL E-LIQUIDS

Although not a standard size, these shortfills usually come in a 60ml bottle, allowing you to use up to 2 nicotine shots. This can achieve a stronger nicotine content over a standard sized shortfill.

10ml 9mg 40ml 50ml total @ 1.8mg/ml
10ml 15mg 40ml 50ml total @ 3mg/ml
10ml 18mg 40ml 50ml total @ 3.6mg/ml
